How one MSP stopped 15 account takeovers in just 30 days

Many businesses using cloud solutions falsely believe that once their data moves to the cloud, it’s automatically protected. However, that’s not exactly the case. According to the shared responsibility model, data protection in the cloud is a shared responsibility between the cloud provider and the customer. Cloud providers secure their infrastructure, but as an MSP, protecting your clients’ user identities, configurations and credentials is your responsibility.

With cloud environments now a critical part of modern business operations, they have also become attractive targets for sophisticated cyberattacks like account takeovers (ATOs) and business email compromise (BEC). In 2024, ATO attacks increased by a staggering 40%, driven by the growing use of AI and machine learning in cybercrime.

In this blog, we will explore how Logically, a fast-growing MSP, stopped 15 account takeover attacks across client tenants with SaaS Alerts.

Turning log noise into actionable threat intelligence using the “Respond” module

Logically leveraged the Respond module in SaaS Alerts to create custom rules based on a combination of SaaS Alerts events to automatically respond to and secure user accounts.

By fine-tuning these rules, Logically focused on high-value indicators of compromise (IoCs) such as:

• Logins from unauthorized or unusual locations
• Sudden creation of inbox rules (a common tactic in business email compromise)
• Multiple failed authentication attempts or MFA fatigue patterns

Rather than reacting to isolated alerts, they began stacking responder rules to identify correlations — two or three combined signals triggered a verified security incident. This layered detection reduced false positives and improved accuracy significantly.

Responding faster, reducing risk

SaaS Alerts’ Respond module enabled Logically to take immediate, automated actions whenever a threat was detected. It allowed them to temporarily lock compromised accounts, block new login attempts, eject threat actors and restore user access safely.

With a system in place to collect and analyze logs, Logically was able to identify threat patterns more easily and respond to them efficiently. This drastically reduced response times, minimizing downtime and disruption.

In cases such as payment or fund redirection scams, which often unfold over days or weeks, the MSP can now intervene quickly and automatically at the first sign of a threat — cutting off attacks before real damage occurs.

Adapting to evolving threats

When attackers evolve, your defenses should too. After discovering a threat actor bypassing MFA through MFA fatigue attacks (after six weeks of repeated attempts), Logically quickly created new responder rules to detect excessive MFA failures and automatically revoke compromised credentials.

SaaS Alerts’ adaptability and powerful SaaS threat detection and response capabilities empower MSPs like Logically to evolve as threat actors change their tactics. With SaaS Alerts, Logically gained complete visibility into their clients’ SaaS environments, helping them monitor, detect and respond to ATO threats quickly and efficiently. In just one month of using SaaS Alerts, Logically stopped 15 account takeovers.
